question 11
what is the minimum configuration for a router interface that is enabled for ipv6?
to have both a link - local and a global unicast ipv6 address
to have both an ipv4 and an ipv6 address
to have a self - generated loopback address
to have a link - local ipv6 address

Explanation:

In IPv6 - enabled router interfaces, a link - local IPv6 address is automatically generated when IPv6 is enabled on the interface. It is the minimum requirement for basic link - layer communication. A global unicast address is not always immediately required for basic operation, having both IPv4 and IPv6 is not a minimum for just IPv6 - enabled interfaces, and a self - generated loopback address is not the minimum configuration.

Answer:

To have a link - local IPv6 address
